DGS-6604 m show arp show arp Use the show arp command to display the Address Resolution Protocol (ARP) cache. show arp [ ARP-MODE ] [IP-ADDRESS [ / MASK ] ] [ INTERFACE-ID ] Syntax Description ARP-MODE (Optional) Displays the entries that are in a specific ARP mode. This argument can be replaced by one of the following keywords: dynamic-Displays only dynamic ARP entries. A dynamic ARP entry is learned through an ARP request and completed with the MAC address of the external host. IP-ADDRESS [/MASK] INTERFACE-ID static-Displays only static ARP entries. A static ARP entry is a statically configured (permanent) ARP. (Optional) Displays the entries associated with a specific host or network entry that is associated with an external host. (Optional) Displays only the ARP table entries associated with this interface such as, for example, a VLAN interface such as vlan100. Default Command Mode Usage Guideline Example None User EXEC mode or any configuration mode ARP establishes correspondences between network addresses (an IP address, for example) and LAN hardware addresses (Ethernet addresses). A dynamic record of each correspondence is kept in a cache for a predetermined amount of time and then discarded. The predetermined amount of time can be changed using the arp timeout command. If no arp mode argument is specified, then all of the arp entries are displayed. The user can select to display a specific ARP entry, all ARP entries, dynamic entries, static entries, or entries associated with an IP interface. This example shows how to display the ARP cache. The field of IP Interface is indicated with the Interface ID.
